I have an ipod.... And i saw my friend had one also.... I asked him what generation it was... And he said it was 4g.... I told him my was 3g.... He said it wasnt because it had a camera... And i looked up on the internet for any source for a 3g with a camera... And none had a camera... So i looked at my udid and it said it was 3g with iphone system.... I got my ipod before the 4g came out.... And it was ios 4.0.1 ....
